Discussion Question: In this research study, one group was asked to watch a car accident and were asked to estimate the speed of the car after it "hit" the other car, while a different group also watched an accident but instead were asked to estimate the speed after the cars "collided." Explain why an independent samples t-test was used, and give an example of a research study in which an independent samples t-test would be the appropriate statistical analysis.

Answer #1

Independent Samples t Test compares the means of two independent groups in order to determine whether there is statistical evidence that the associated population means are significantly different. The Independent Samples t Test is a parametric test.For example, you could use an independent t-test to understand whether first year graduate salaries differed based on gender (i.e., your dependent variable would be "first year graduate salaries" and your independent variable would be "gender", which has two groups: "male" and "female"

Loftus and Palmer study (1974) demonstrated the influence of language on eyewitness memory. Participants watched a film of a car accident and were asked questions about what they saw. One group was asked “About how fast the cars were going when they smashed into each other?” Another group was asked the same question, except the verb was changed to “hit” instead of “smashed into”. The ‘smasher into” group reported significantly higher estimates of speed than the hit group. Suppose a...

1. In 1974, Loftus and Palmer conducted a classic study demonstrating how the language used to ask question can influence eyewitness memory. In the study, college students watched a film of an automobile accident and then were asked questions about what they say. One group was asked, “About how fast were the cars going when they smashed into each other?” Another group was asked the same question except the verb was changed to “hit” instead of “smashed into.” The “smashed...

Instructions: Recall the “Witness” study from your t-Test crash course. Research in legal psychology shows that eyewitnesses are greatly impacted by the manner in which investigators phrase their questions. For example, in 1974, Loftus and Palmer conducted a study where they had participants watch a video clip of a car accident and then answer questions about what the participants just witnessed. They assigned participants to one of two conditions where they altered the phrasing of one important question: How fast...

A study was conducted to determine whether the mean braking distance of four-cylinder cars is greater than the mean braking distance of six-cylinder cars. A random sample of 20 four-cylinder cars and a random sample of 20 six-cylinder cars were obtained, and the braking distances were measured. (a) What would be the appropriate hypothesis test for this analysis? (i) t-test for two independent samples (ii) t-test for dependent samples (iii) z-test for population mean (iv) correlation (b) Explain the rationale...

Loftus and Palmer studied the relationship between implicit recall cues and memory. They manipulated the wording in questioning subjects about an accident they had viewed on film. Students were shown a multi-car accident and then given a questionnaire asking them to recall details of the collision. One group of subjects were asked to estimate how fast the cars were travelling when they "hit" each other, while the other group was asked to estimate how fast the cars were travelling when...

Identify a research question from your professional life or career specialization (youth development) that can be addressed by an independent samples t test. Indicate why a t test would be the appropriate analysis for this research question. Describe the variables and their scale of measurement. Discuss the expected outcome (for example, "The Group 1 mean score will be significantly greater than the Group 2 mean score because…")

10) A professor has asked a group of students to study prison data for a class project. They were given a random sample of data from a nearby prison. They wanted to study the relationship between an prisoner's race and the type of offense committed for the conviction.    a)            Identify the level of measurement for each variable. b)            What inference test (hypothesis test) would be used to carry out this research analysis? 11) State the Null and Alternative Hypotheses for the research...

Question: Imagine a replication of Craik and Lockhart's study was done in which three groups were asked to engage in different study strategies. After reading a list of words, one group of participants had to use maintenance rehearsal (i.e., repeating the word over and over), one group had to use elaborative rehearsal (i.e., connecting the word to a category) and a third group had to use a different elaborative technique (ie., using the word in a sentence). Explain why an...
